After officially placing defensive end Andre Carter on Injured Reserve and releasing defensive end Eric Moore earlier on Tuesday, the Patriots have two roster spots to fill on their 53-man roster.

Fuller, a fourth-round pick of Tennessee in 2005, has played in 76 games over the course of his career. The 6-foot-1, 192-pound defensive back has experience playing nickel/slot corner and can also play safety. The 29-year-old adds a versatile and veteran presence in a suspect New England secondary struggling to defend the pass this season.

With Fuller expected to sign, the Patriots will have one more roster spot to fill on their active roster. Either Markell Carter or Alex Silvestro from the team's practice squad could be an option for the Pats. My guess is Carter will be promoted after the team doubled his salary earlier in the week.

The sixth round draft choice has been making strides on the practice field and bulked up to around 268 pounds. Carter saw a raise in his salary to more than 300, 000 after another NFL team offered to sign him to their roster. Perhaps he is ready to make the jump this week to fill the team's roster void. In any case, the other roster transaction should also be announced today.
